We battery-tested top tablets from Apple, Samsung, and others in our lab: These were the winners
ZDNET tested flagship tablets in our lab to find out which tablets have the best battery life.
In our Louisville-based lab, we tested each tablet using a dedicated PC with an NI USB-6001 DAQ, eight auxiliary inputs with adapters, and LabVIEW software coded in-house to analyze audio outputs as voltage signals. This was chosen due to its availability on all operating systems, relative name recognition with the general public, and compatibility with the level of settings control the lab team wanted to exert. As you can see from our data visualization (Figure 1), we found that the iPad Pro has the most impressive battery life at over 16 hours before having to be charged, solidifying its rank as the best tablet for power users or as a laptop replacement.
